In the image above you can see that the three valve buttons have been painted to correspond to frets on the original guitar controller. The orange and blue frets are positioned for the left hand to operate. There seems to be a couple of different version because there is a diagram showing a mute in the bell that can be twisted for whammy bar input, but that’s not shown here. Strumming is accomplished by blowing through the mouthpiece, but as you can see in the video after the break, no buzzing is necessary.

Haha thanks for running this! I just did a short open dork presentation with the trumpet (cornet) seen above, and another converted horn at Dorkbot SF tonight. They both have star power functions, and whammy bars, also the orange and blue buttons are accessible with left hand.
